you should use sumproduct. a sample:

=sumproduct(--(a2:a100=g2)*(b2:b100h2)*(b2:b100<i2),(c2:c100))

whe

g2 contaim the item code that excel will check on column A
h2 has the start date that will be check on column B
I2 has the end date
and column c has the values that you would like to sum.

change the ranges as you need.

I have a worksheet(1) that is setup as follows:
Col A ColB ColC
Item# Date Qty

Worksheet(2)
ColA ColB ColC ColD
Item# Start Date End Date (result)

I am trying to write a function that will look for info in cell A5 in
worksheet 2 and find the info in column A in worksheet 1 check that the date
in column B being between a date range and then returning a sum of the totals
of the corresponding rows of column C in worksheet 1. I hope this makes
sense..I'm not sure how else to explain it.
